The first article written by Prof. Robert Hewsen of Georgetown University on the meliks (princes) of Eastern Armenia, ie Syunik and Artsakh (Karabagh). This article, like the three following (out of six), are difficult of access because published in the French Revue des Etudes Arméniennes which only a few institutions outside France shelve. These articles are fundamental to understand the Armenian principalities of the 15th to 19th century.
